FELIX FRANK, F CLEVELAND OHIO.

vJana-ooont-iver APPARATUS.

To all whom it my concern:

Be it known that I, FELIX FRANK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Air-Cooling Apparatus, of which the following is a specification.

This invention relates to air coolers and has for its object the provision of a comparatively simple and inexpensive device of this character especially adapted for installation in dwelling houses, churches, ffactories, hospitals, hotels and other places, for

cooling and promoting the circulation of air I in warm weather. I r

A further object is to provide a cooling apparatus in which warm air is directed through a chamber containing ice or other refrigerant for delivery to the interior of a room or otherv inclosure.

A further object is to provide an air cooler including inner and outer receptacles spaced apart to form an intermediate air circulating chamber, one of said receptacles being provided with superposed ice and water receiving compartments respectively and having coil pipes extending therethrough and communicating with a discharge pipe.

Further objects and advantageswill appear in the following. description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

' For a full understandin of the invention and the merits thereof an also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of an air cooler constructed in accordance with my invention; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a vertical sectional view showing the cooler in position onthe roof of a building and employed for cooling the air in the several rooms of said building.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters. a

The device comprises an outer receptacle 5 of any suitable contour or cross sectional formation and preferably formed of spaced plates between which is interposed a non- Specification of Letters Patent; Application filed December-10, 1909. Serial No. 532,389;

Patented Mar. 12,1912.

*spaced from'the latter to form an intermediate air circulatingchamber 10, said inner receptacle being provided with a'transversely disposed perforated partition 11 defining superposed compartments 12 and 13,- one of which is adapted to contain a quantity of ice 'or other refrigerant and the other the water produced by the melting of said ice.

The inner receptacle 8 is provided with a lid or cover 14: having a plurality of perforations 15.formed therein, there being simi lar perforations '16 formed in the side walls of .the compartment 12 so as to permit the passage of air through the ice in the compartment 12 into the intermediate air chamber 10 for the purpose of cooling the air prior to its delivery to the rooms of a building.

Disposed wlthin the compartment 12 are a series of'coil pipes 17 having funnel shaped mouths 18 and straight depending portions 19, which latter extend through the lower water receiving compartment 13 and are provided With flared portions 20, similar in construc-' tion to the flared portions 18 so that a portion of the air entering through the perforations in the'cover 1 1 may be cooled without coming indirect contact with the ice. If desired however, these coil pipes 17 may be dispensed with without departing from the spirit of the invention.

The intermediate portion of the partition;

11 is preferably bent or dished downwardly so as to facilitate the discharge of the Water in the upper compartment 12 through the perforations in said partition, there being a drain21 communicating with the lower co1n partment 13 to permit the discharge of the water therein,'when.desired.

The partition 11 is preferably extended laterally beyond the side walls of the inner receptacle 8 to form a circumferential trough 22 designed to catch any water that may pass through the perforationsllfi and direct the same: into the compartment 13. A discharge pipe 23 communicates with the air chamber 10 at the bottom of the outer receptacle 5 and through which the cooled 'air is conductedto the interior of a room or other inclosure.

The pipe 23 may be connected. directly to the bottom of the outer receptacle 5 orthrough the medium of a relatively short flexible conductor, indicated at 24.

Supported on'a spider 25 arranged above the discharge pipe 23,.is a fan 26 'which serves to draw the air through the perforations in thecover let and side 'wallsof the inner receptacle 8 and force-said air down wardly through the discharge pipe 23, thus to promot'ethe circulation of air and cause the cool air to be continuously discharged through said pipe into a room. If desired however, a suitable pump may be substituted for the fan 26, or said fan entirely dispensed with as may be found desirable or necessary to the proper working of the device or the conditions under which it is used.

Secured to the top of the outerreceptacle 5 are eyelets 27 having suspension cords or chains 28 secured thereto and adapted to be 7 attached to a ceiling or other suitable support for the purpose 'of suspending the device within a room or other inclosure.

Thus it will be seen that the warm air entering through the perforations in the cover 14 and coming in contact with the ice or other refrigerant in the upper compartment 12 will be cooled and pass through the openings 16 in the walls of the inner re-- ceptacle and thence intothe chamber 10 where it will pass downwardly through the discharge pipe 23, as before stated, a 'portion of the air entering through the perforations in the cover 14: being directed through the coils 17 and flared portions 20 into the chamber 10 immediately above said from a ceiling or supported on the roof of a building as the same may be used with equally goodresults when positioned in a cellar, in which event a fan or pump willof course be employed for promoting the circulationof air within the several supply pipes. 7
